Duan, Lu-meng;Chen, Ting;Li, Zhong-qing;Li, Ji-xiang;Ma, Ze-qun;Liang, Xian-li;Hang, De-yu research published 《 Synthesis of high purified 2-bromobenzo[9,10]phenanthrene》, the research content is summarized as follows. The target compound is an important intermediate in some fields such as organic luminescence, disk liquid crystal and biomedicine. The synthesis method of high purity target compound is rarely reported in literatures. 2-Biphenylboronic acid was prepared from the starting material 2-bromobiphenyl by lithiation reaction at ultra-low temperature, and then (2-nitro-4-bromophenyl)-1-1′-biphenyl was obtained from 2-biphenylboronic acid and 2,5-dibromonitrobenzene by Suzuki coupling reaction, which was reduced by iron powder to obtain (2-amino-4-bromophenyl)-1-1′-biphenyl, finally the title compound (I, CAS Number 19111-87-6) was prepared by ring closure with isoamyl nitrite. Synthetic route of the compound was easy to operate, and the raw materials were easy to obtain. The target compound was suitable for industrialization and market high standard quality demand because of high purity. The structures of the each step compound were confirmed by 1HNMR and 13CNMR, the purity was determined by HPLC, and the performance of target compound was tested by DSC and TGA.
Application In Synthesis of 19111-87-6, 2-Bromotriphenylene is a useful research compound. Its molecular formula is C18H11Br and its molecular weight is 307.2 g/mol. The purity is usually 95%.
2-Bromotriphenylene is a brominating agent that has the ability to react with sodium carbonate and emit light. The luminescence of 2-bromotriphenylene can be used as an indicator of the degree of dilution, or how much water is present in a solution. It also emits light when it reacts with chloride ions in a reaction solution. 2-Bromotriphenylene can be used as a polymer matrix to form polymeric films, which are then used as catalysts for organic reactions. The luminescence properties of 2-bromotriphenylene make it suitable for use in functional theory experiments. This chemical compound is relatively low cost, and has been shown to have high yield in catalysis., 19111-87-6.
